USB: s3c2410_udc: fix custom UDC command handling

Browse Source 
There is a bug in Samsung's UDC driver, which is completely disabling
the USB device when a custom UDC command is used.
Following patch seems to get the right behavior (e.g. enabling pull-up
instead of disabling then Vcc is applied).
